In an obvious mental tactic, Floyd Mayweather Jr. has invited WBA lightweight champion Brandon Rios, and his trainer Robert Garcia, to attend Saturday's fight at the MGM Grand in Las Vegas. Mayweather will challenge Victor Ortiz for the WBC welterweight crown. The bad blood between Ortiz and Rios/Garcia is well documented. Garcia used to train Ortiz before the two of them had a serious falling out. Ortiz left Robert in favor of his older brother, Danny Garcia. The Garcia brothers have barely spoken to each other in years. Ortiz and Rios, once close friends, are now mortal enemies.
